IE8 hangs up and even Task manager will not run

When I run IE8 it will periodically hang my system so badly that even Task Manager does not run. I noticed that when I start IE8 it shows TWO copies in task manager. I have attached a hijack this log of my system.
I have gone into IE8 manage add ons and disabled all of them to see if that solves the problem. I think something is periodically going out to the internet for an update check but I have disabled update checks. I do use a time sync service.
